GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 744,375, dated November17, 1903. Application filed March 21, 1903. Serial No. 149,001. (Nomodel.)

To @ZZ whom t may concer-7c:

Be it known that I, JOSEPH A. LUSSIER, of

Minneapolis, county of Hennepin, State of lconstructions andcombinations, all as herein-V after described, and in the claims.

In the accompanying drawings, forming part of this specification, Figure1 isa section of a grain drill embodying my invention. Fig. 2 is a rearviewof the same. Figs. 3 and 4 are details showing the manner ofattaching the shoe to the boot. Fig. 5 isa detail of the connectionbetween the spring and the boot.

In the drawings, 2 represents a portion of the frame of the machine, tothe forward end of which the drag-bar 3 is pivotally connected. Thedrag-bar is secured to a shoe 4, that is provided at its rear end with apin 5 to particularly pointed out enter slots 6 in the boot 7, whoselower end isV adapted to pass between the sides of the shoe at its rearend. The shoe 4 is provided with holes 8 in advance of the pin 5 toreceive pins 9, provided on said boot in advance of the slots therein. Iprefer to provide the slots in the boot and the pin to enter the same onthe shoe, as the boot after the pins 9 are inserted into the holes 8 andthe pin 5 enters the slot 6 will have two supporting-bearings to sustainany sudden shock resulting from the shoe striking an obstruction insteadof only one bearing, which would he the case were the positions of thepin 5 and the slots 6 reversed. The boot is provided at its upper end oneach side with lugs 10, and a fork 11 has bent ends 12, that are adaptedto pass under said lugs and be held in engagement therewith by stops 13.This fork 11 extends vertically above the boot and is provided at mediumof the fork 1l will normally exert a direct downward pressure on theboot to force Athe shoe into the soil and allow it to adjustitselfautomatically to the different conditions of the soil and alloweach shoe to pass over au obstruction independently of the other shoes.The stops 13, engaging the lower end of the fork, will prevent it frombecoming detached from the lugs 10 when the pressure of the spring isexerted on the fork.

By means of the lever 18 the operator can -lock the shaft 16 and raisethe spring l5 and the fork to the position indicated by dotted lines inFig. 1.

I am aware that spring mechanisms have been provided heretofore forapplying a yielding pressure' to the boot and the rear end of the shoe,and I do not, therefore, in this application make claim, broadly, tosuchconstruc- .tion, the essential features of my invention being themanner ofapplying such yielding pressure to the hoot to bring about thedesired direct spring-pressure longitudinally of the boot to force theheel of the shoe into the ground, the simplicity of the device resultingfrom the omission of many parts usually employed and the improvement inthe manner of securing the shoe and boot together.

I claim as my invention- 1. In a grain-drill, the combination, with adrag-bar, of a shoe, a boot mounted on said shoe, a rock-shaft providedwith an operatinglever, a spring secured at one end to said shaft andhaving a plurality of loose coils thereabout, the free end of saidspring being pivotally connected with said boot and its path beingunobstructed to permit the shoe to drop into depressions in the soil andaccommodate itself to an uneven surface.

2. In a grain-drill, the combination, with a shoe and a hoot mountedthereon, of a rockshaft provided with an operating-lever, a springsecured at one end to said shaft and IOO having a pivotal connection atits other end with said boot,and the path of said pivoted end beingunobstructed to allow said shoe to drop into depressions in the soil andaccommodate itself to an uneven surface.

3. In a grain-drill, the combination, with a frame, of a drag-barpivoted thereon, a shoe connected to said drag-bar, a boot mounted onsaid shoe and havinglugs 10 and stops 13, a member having a fork at oneend provided with bent ends that pass between said lugs and said stops,said member extending vertically above said boot,a flat spring looselyconnected at one end to said member, and a rock-shaft having anoperating-lever and around which shaft the other end of said spring iscoiled and secured.

4. In a grain-drill, the combination, with a boot, of an upright memberpivoted thereon in line substantially with its Vertical axis, a.rock-shaft, a spring secured at one end to said shaft and having aseries of coils thereabout and connected at its free end to said memberand arranged to exert a vertical thrust therethrough upon said boot.

5. The combination, in agrain-drill, with a drag-bar, of a shoe securedthereto and having oppositelyarranged holes 8 in its sides, a pin 5connecting said sides in the rear of said holes, and a boot adapted topass between the sides of said shoe and having pins 9 to enter saidholes, and forwardly-extending slots in the rear of said pins 9 toreceive said pin 5, substantially as described and for the purposespecified.

In witness whereof I have hereunto set my hand this 7th day of March,1903.

l JOSEPH A. LUSSIER.
